Description

The Keraflo Aylesbury “KB” Type Fully variable Delayed Action Float Valves are ideal to provide an accurate and efficient method of controlling the level of stored water in cold water storage tanks without a lid or raised chamber and where the vertical drop from the valve to the water level may be considerable.

When the water level inside the tank falls the “KB” type valve does not immediately open, there is a delay until the water level has fallen to the user selected level, when this occurs the valve moves from a fully closed to a fully open position allowing water to flow back into the tank at a maximum flow rate, when the water level has returned to it’s full level the valve closes preventing any dribbling. This action provides a range of benefits including improved water turnover, fast refilling times, no water hammer and reduced noise.

Pumps and pump sets are often controlled to run for a minimum of 3 minutes. If the water demand is satisfied before this time and an auxiliary hydraulic accumulator is not fitted, the pumps will run against a closed valve head at zero efficiency.

The fill volume can be set to equal or exceed this volume to ensure the pump(s) run for at least 3 minutes. Where a pump set is used solely for transferring water from a break tank to an elevated storage tank, the ‘KB’ valve can dispense with the need for an auxiliary hydraulic accumulator.
